IMPROVEMENT IN CURRENT WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the name.

To whom ct may concern Be it known that I, HEMAN B. SINCLAIR, of Paw Pawfiu the county of Van Burenand State of Michigan, have invented a new and useful Improvement'in Current Water-Wheels; and I do declare that the .following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Fjgure l is a perspective view of my wheel, and Figure 2 is, a plan view. I I

Like letters. indicate like parts in each figure. The nature of this invention relates to an improved construction of currentweter wheels, and of guides B, connected at the top by a suitable string-piece or girder, a. v I

O is a vertical shaft stepped in suitable bearings in the ibundation, its upperlend being journaled in the girder a i A suitable gear or band-wheel on the upper end of this shaft gives motion to the machinery to be operated by the wheel.

a hub rigidly secured to the shaft 0 at its lower end.

From this hub radiate a number of'arms, 0, their outer ends being-connected to oneanother by peripheral brace-rods :1.

Upon the radial arms are hinged, at their upperedges the blades F.

fare chains leading from one radial arm to the bottom of the blade next, preceding it, and is of such length that the blades moving with the current willassume a vertical position, on which the current acts a to compel the rotation of the wheel, while the blades on the other side of the. 'wheel may swing up and feather while moving against the current.

G is a deflecting-gui e extending from the lower to" the upper uprights of 'the frame immediately above the'whel, the later upright being set back toward the shore so as to deflect descending drift-wood to the working side of the wheel, so that, even if the drift-i wood should come in contact with a blade, it woiild pass out asjsoou as the blade became tangent to the 'cnrrent.

, What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of a current water-wheel provided with the hub E, the radial arms 0, the blades h, the

brace-rods D, and the ohainsf, with the deflectingguide G, all constructed aud arranged substantially as described and shown, for the purpose set forth.
